Ride Height - Is an Adjustment Required?

One example is shown here: Motion Pro #08-0029 wrench It works well but is thin, so wear some heavy work gloves while pushing on it. Also, it doesn't exactly fit the rear adjuster on my 90 GT's Boges, though the 'tooth' is secure in the holes on the ajduster.
928 Specialists also lists one that has a nicer looking handle, yet half the price. Never seen this one in action
Finally, Dr. Bob has a set of three which ratchet- I think he said were Harbor Freight but I've not been able to find them there. They were really cool, although the handles were shorter and thus a bit of a workout.
As far as measuring ride height, I also took a page from the Dr. Bob book and whipped these sticks up out of coat hanger. Total cost: about $0.07, plus dry cleaning.....

Another sage advice: Wear gloves when using this tool. Your hands will be skinless if you don't! Those perches are HARD to turn! Squirt some oil on them prior to trying this.

The wrenches I use are genuine Harbor Freight tools. Set of four sizes was about $15 IIRC. Sold in a box, with a plastic roll-up pouch. The wrences have pivot pins in the midle that make them tolerant of a larger array of ring diameters. In my opinion, they work better than the rigid ones like the Motion Pro. I can go get the part no if you folks need it.
No matter which wrench you use, get the crud and the undercoating off the threads before you even try to move them. A generous dosage of spray lubricant will make your arms and hands a little less uncomfortable, especially if you do the adjustments with the suspension fully loaded. You'll still end up driving the car some between twists on the rings. The whole thing is an ioterative process, especially considering that the measuring spots aren't between the tires but are fore or aft of them.

The Harbor Freight tools I have are in set 41243, which of course does not show up at a search at their website. I went through this before when I bought them-- No listing on the website but found them at the local store (Pasadena, Ca). They were in and out of stock there, and they happened to be there one time when I was actually thinking of doing the work so I grabbed them. I had previously been using a less elegant spanner that was a bit too small, but still did the job with a fight.
If you happen to be near a Harbor Freight store, you may be able to locate these. It may also be worthwhile to ask at the store, since there is an obvious disconnect between what they offer there and what's on the website.

The measuring points are easy to reach by lying down and reaching under and in. There are many ways to measure. I tried pointers and coat hanger sticks and worryied about not getting them exactly vertical. Tthe points are easy to reach but hard to see at the same time and a tilt to the stick will change the height measurement - think about the height of a triangle.
I finally used a carpenter's angle finder to take the height (one side can be flat on the ground) and then measured the height with a ruled square after I'd removed it. It worked a treat.
When I got my car it was at 124mmF and 128mmR. I figure that's why I wiped an alternator off on the road.
I'm lucky I kept my compressor and block.

Why, pray tell does the WSM advise us to have:
1. The proper - or at least static/the pressure you plan to live with - air pressure in our tires.
2. The approximate weight of driverloading in the drivers seat. (Why no avg. pass. weight in the Pass. seat?)
3. The proper ride height measured from the duly identified measuring points.
Not to unload the suspension unless You have the Porsche 'loading tool' that will keep the sHARk at recommended ride height during the alignment.
I believe there is a reference to springs, shocks, links, balljoints etc... made somewhere as well.
Prior to performing the alignment.

In the lowered car, smaler changes in suspension hight make bigger changes in toe, since the tie rods now angle up from the ends of the rack to the outer tie rod ends at the spindle. A small amount of compression common with cornering and with any freeway driving will cause the front wheels to toe out.
